account_import · HashPilot MCP: Risk & Policy

WHAT IT DOES

What account_import does on HashPilot

AI agents use account_import to create or update resources in HashPilot — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your HashPilot environment.

WHY IT NEEDS A POLICY

Why account_import needs a policy

This is a Write operation because it creates/adds a new entry to the address book (a persistent data structure), which is a reversible modification. However, severity is elevated to 'high' rather than medium because the tool handles sensitive authentication material (private keys).

From the tool's definition Tool description states 'Import an existing Hedera account into the address book' and accepts 'account ID, private key, and alias' — this modifies the address book by adding/storing a new entry. The tool reversibly creates a new address book record.

Verdict

account_import Rate-limited

account_import stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
